Trial Outcomes & Findings for Belatacept Compared to Tacrolimus in Deceased Donor Renal Transplant Recipients (NCT NCT02152345)

NCT ID: NCT02152345

Last Updated: 2021-02-10

Results Overview

To assess whether treatment with Thymoglobulin induction and belatacept based maintenance immunosuppression would reduce delayed graft function (DGF) rates among recipients of deceased donor renal transplants as measured by clinical findings and NGAL marker, as specified below and defined by others. This will be compared to the incidence of DGF in patients treated with a Tacrolimus based regimen. Patients who require hemodialysis in the first 7 days after transplantation and/or patients whose serum creatinine decreases \<10% during 3 consecutive days after the transplant will be considered to have DGF in the absence of other confounding factors such as obstruction or infection. NGAL will be used as a verification marker of DGF.

Belatacept Immunosuppression
Renal transplant recipients will receive Methylprednisolone, rATG, Belatacept and Mycophenolate. Subjects will be followed for primary endpoint to Day 7 and Month 3 after transplantation and secondary endpoints of kidney function and patient and graft survival up to month 36 after transplantation. Belatacept 10 mg/kg will be administered in the operating room \~1 hr prior to kidney allograft reperfusion (Day 0). It will then be administered at 10 mg/kg on the following post-transplantation days: 5, 14, 30, 56, \& 84. Belatacept 5 mg/kg will be administered every four weeks thereafter until end of study. Standard of Care: * Mycophenolate: 720 mg by mouth every 12 hours (Day 0)(1080 mg AA). * rATG: 1.5 mg/kg IV daily on Day 0-3. * Methylprednisolone: 500 mg (Day 0), 250mg (Day 1), 125mg (Day 2), 75 mg (Day 3) IV administered Day 0-3.
Standard Immunosuppression (Tacrolimus)
Renal transplant recipients will receive standard immunosuppressive therapy, including steroids (Methylprednisolone), rATG, Tacrolimus and Mycophenolate. Subjects will be followed for primary endpoint to Day 7 and Month 3 after transplantation and secondary endpoints of kidney function and patient and graft survival up to month 36 after transplantation. Tacrolimus 0.05 mg/kg PO every 12 hrs will be on Day 0 after transplantation. It will then be administered on the following post-transplantation days: 3-90 at 8-12ng/mL; Day 91-180 at 8-10 ng/mL. Standard of Care: * Tacrolimus 6 - 8 ng/mL administered daily thereafter until end of study. * Mycophenolate: 720 mg by mouth every 12 hours (Day 0)(1080 mg AA). * rATG: 1.5 mg/kg IV daily on Day 0-3. * Methylprednisolone: 500 mg (Day 0), 250mg (Day 1), 125mg (Day 2), 75 mg (Day 3) IV administered from Day 0-3.
